Abstract

A semiconductor integrated circuit for monitoring a switch, including: a first detection part that detects a state of a first switch; a second detection part that detects a state of a second switch; a sub-voltage monitoring part that monitors whether the sub-voltage is within a predetermined range; a switch monitoring part that monitors a change in a state of the first switch and a change in a state of the second switch; a setting part that determines an invalid period, during which the monitoring result of the switch monitoring part regarding the change in the state of the second switch is invalidated; and a transmission part that transmits the monitoring result of the switch monitoring part and information on the invalid period.
